As it has already beeing said, you never defrag an SSD!
From one side, it does not improve anything on the reading speed as there are no mechanical parts involved in the reading data process.
From the other side, SSDs have they own internal system to write data onto different sectors every time, in order to avoid overusing the same area.
As the memory chips have a limited number of "write" times, writing continously on the same area will eventually lead to a failure (that particular area can not be used any more).
This is normaly no problem as the internal SSD system knows how to cope with it and stops using that specific area and reallocates any data elsewhere (this process happens in the background and the user notices nothing of it). For exactly this reason, at least in the past (I have no idea about newer SSDs) we used to never allocate the full size of the SSD but instead leave some 5% unallocated which could be used by the SSD system to replace any overused areas.

How old was your SSD hard disk? It is still rather strange that it happened.
The disk does not boot because one of the boot files for Win7 is damaged. OK with that.
But, if you connect the disk as a second hard disk on another PC, can you read te contents of the disk? Normally you should...
It can also be that a file was damaged and that replacing it would solve the problem.
Anyway, it is not worth experimenting if it is only $120 for the replacement.
But I believe you would probably be able to use your old SSD still. Just in case, this time, do not particition the whole SSD but leave 5%-10% unallocated.
